Abstract (en)

A vortex generator device (70) for mounting on a wind turbine blade (10) is disclosed. The device comprises: a base (71) having, when mounted on an exterior of the wind turbine blade (10), an inner side (72) for attaching on a surface, such as the exterior of the wind turbine blade (10), and an outer side (73) facing away from the exterior of the wind turbine blade (10). The vortex generator device is provided with at least a first vane (79, 80) protruding substantially perpendicular to the base (71) from the outer side (73), wherein the vane (79, 80) comprises a leading edge side (78) for arranging nearest a leading edge of the wind turbine blade (10), and a trailing edge side (77) for arranging nearest a trailing edge of the wind turbine blade (10), and wherein the vane (79, 80) comprises a leading edge portion (83) located nearest the leading edge side (78) of the vane (79, 80), which is tapered towards the leading edge side (78) of the vane (79, 80). The vane (79, 80) further comprises a trailing edge portion (85) located nearest the trailing edge side (77) of the vane (79, 80), which is tapered towards the trailing edge side (77) of the vane (79, 80), and/or the vane (79, 80) is tapered towards a top part of the vane (79, 80).
